Question

Бобёр принёс 3 мешка ячменных зёрен и 5 мешков пшеничных.Масса мешка с ячменными зернами в 3 раза больше,чем с пшеничными.Найдите массу каждого мешка,если он принёс 252 кг зёрен?

Answer 1

Слушай, может и бред, не знаю, но может и оно:

Массу мешка возьмём за х, тогда получится

3х + 5х = 252, но дело в том, что масса мешка с ячменными зёрнами в 3 раза больше, тогда наверное так

3*3х + 5х = 252

14х = 252

х = 18.

Не уверен, честно.

Answer 2

масса мешка пшеницы - x

тогда масса мешка ячменя - 3x

5 мешков пшеницы - 5x

3 мешка ячменя - 3*3x

5x + 9x = 252

14x = 252

x = 252/14 = 18 кг пшеницы в мешке

3x = 3*18 = 54 кг ячменя в мешке

ПРОВЕРКА: 3 * 54 + 5 * 18 = 162 + 90 = 252

Answer 3

Problem Analysis

We are given that a beaver brought 3 bags of barley grains and 5 bags of wheat grains. The mass of the bag with barley grains is 3 times greater than the mass of the bag with wheat grains. We need to find the mass of each bag if the total mass of the grains brought by the beaver is 252 kg.

Solution

Let's assume the mass of a bag with wheat grains is x kg. According to the problem, the mass of the bag with barley grains is 3 times greater than the mass of the bag with wheat grains. Therefore, the mass of the bag with barley grains is 3x kg.

We know that the beaver brought 5 bags of wheat grains and 3 bags of barley grains. The total mass of the grains brought by the beaver is 252 kg. We can set up the following equation to represent this information:

5x + 3(3x) = 252

Simplifying the equation:

5x + 9x = 252

14x = 252

Solving for x:

x = 252 / 14

x = 18

Therefore, the mass of each bag with wheat grains is 18 kg.

To find the mass of each bag with barley grains, we can substitute the value of x into the equation:

3x = 3 * 18 = 54

Therefore, the mass of each bag with barley grains is 54 kg.

Answer

The mass of each bag with wheat grains is 18 kg, and the mass of each bag with barley grains is 54 kg.
